The aim of this study is to clarify the rhetoric of integration on deformed roof shape in Japanese contemporary houses. When a house is built, “regular shape” can be used in a large site, but “deformed shape” must be used along the limits of small sites and in dense areas. With the deformed roof there is a possibility for s dynamic conflict between the rule of the basic roof shape and the possibility of each specific condition. In this study, the roof shapes are analyzed in terms of certain roof components: eaves, ridge, pitch of the roof, also, by surveying houses with the shed-roof deformation, the gable roof, the pyramidal roof and the hipped roof are considered. As a result, roof deformation are defined by the combination of the deformed parts. Thus the rhetoric of integration on deformed roof shape is revealed through the comparison of the each character beyond the basic roof form.
